NASAI-KUBRA 6272:
from Sulaymān b. Jābir —
[Machine] Abdullah bin Mas'ood said: "Indeed, the Messenger of Allah ﷺ said, 'Learn the Quran and teach it to the people, learn and teach the obligations (i.e. religious duties), and learn knowledge and teach it to the people. For indeed, I am taking hold of you, and indeed, knowledge will decrease. And trials will appear until two people will differ in a matter of obligation, and they will not find anyone to judge between them.'"
الكبرى للنسائي ٦٢٧٢:
عن سليمان بن جابر —
قَالَ عَبْدُ اللهِ بْنُ مَسْعُودٍ إِنَّ رَسُولَ اللهِ ﷺ قَالَ «تَعَلَّمُوا الْقُرْآنَ وَعَلِّمُوهُ النَّاسَ وَتَعَلَّمُوا الْفَرَائِضَ وَعَلِّمُوهَا النَّاسَ وَتَعَلَّمُوا الْعِلْمَ وَعَلِّمُوهُ النَّاسَ فَإِنِّي مَقْبُوضٌ وَإِنَّ الْعِلْمَ سَيَنْقُصُ وَتَظْهَرُ الْفِتَنُ حَتَّى يَخْتَلِفَ الِاثْنَانِ فِي فَرِيضَةٍ لَا يَجِدَانِ إِنْسَانًا يَفْصِلُ بَيْنَهُمَا»
